PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 408,209, dated August 6, 1889.

Application filed July 2, 1888. Serial No. 278,843. (No model.)

.T0 @ZZ whom, it may concern:

Be it known that I, ROBERT BURNET, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Paper-Feeding Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide a simple and reliably operating mechanism by which sheets of paper may be automatically fed to a ruling or printing machine with rapidity. To this end a frictional feeding-roller carried by a swinging frame or arms is arranged to rest on the pile of sheets of paper to bev fed to the machine, and said roller is driven by a suitable belt or other gearing from the machine to which the paper is to be fed. The feeding-roller is preferably pressed down on the paper by springs acting on the arms by which it is carried in addition to its own weight. To prevent more than one sheet of paperat once from being drawn off from the pile, a spring-pressed friction-clamp, preferably having a bearingface of rubber, is are ranged to press on the sheets of paper near their rear ends, and the friction feedingroller, which is preferably covered with sand or emery, engages the sheets near their front ends and forces them forward to feeding-rolls, which carry them to the machine.

In the accompanying drawings, Figure l is a side view of my invention in connection with a portion of a paper-rulin g machine, and Fig. 2 is a plan view of the same.

A denotes a portion of the frame of the ruling-machine, and B B are the usual feeding-rolls thereof. Said rolls may be operated by the crank-handle b3, or may be driven by power. Attached to the frameA are the supports or brackets O, which sustain the table D, on which the paper E is laid. Attached to the said table, or otherwise suitably supported, are brackets F, in which is journaled the shaft G, and pivotally attached to the said brackets or shaft are arms II, in theouier or free ends of which is journaled the shaft t', carrying the frictional feed -roller I, arranged to rest on the pile of paper on the table D. The feed-roller I has a roughened or frictional periphery or surface of emery, sand,

ets F are the feed-rolls J J', between which passes the cloth carrying-belt a of the rulingmachine.

The shaft of the lower feeding-roll B is provided with a pulley l), which is connected with a pulley g on the shaft G by a belt b, a second pulley g on said shaft being connected by a crossed belt b2 to a pulley t" on thelshaft 'L' of the feedingi'oll I. Thus when the said roll B is rotated (by the crank-handle b3 or otherwise) the feeding-roll Iwill also be rotated to draw the paper from the pile on the table D and pass it to the feed-rolls J J and onto the belt a, which carries it forward onto the ruling-machine. The roll I may be pressed down onto the paper by springs K, the tension of which is preferably rendered adjustable by thumb-screws 7c on adjustingbolis 7d, to which the said springs are attached.

To prevent more than one sheet of paper at a time from being drawn from the pile of paper, I employ a spring-pressed holding or friction device, consisting in the present instance of the arms m, pivoted to brackets M, attached to the table D, and to the free ends of said arms is attached a holdback-bar m', arranged to press on the paper, said bar being faced with rubber or other frictional inaterial, rubber being preferred, as it will have a frictional hold on the paper which will be less than the frictional hold which the surface of the sand or emery covered roller I will have, so that the said roller can draw the sheets of paper from the pile one at a time.

The arms m are pressed down by a spring n, attached to a bar N, connecting said arms, and to a hand-lever O, secured to a rod o, the latter being provided with a thumb-nut p or other suitable securing device, by which said rod and lever may be held in any position to which they may be adjusted.

To guide the paper to the feed-rolls J J', an incline P is interposed between the said rolls and the pile of paper on the table D.

Frein the foregoing it will be apparent that when the machine is supplied with paper, as shown in Fig. i, and the roll B is rotated,

IDO

the paper will be fed to the belt a, passing` thus be automatically1 fed to the ruling-machine. Vhen a fresh supply of paper is to be placed on the table D, the thumb-nut p is loosened,'leaving the hand-lever O and arms m free to be lifted to release the holdback or pressure bar m from the table out of the way of the new pile of paper to be placed thereon.

My invention, while herein shown as being connected to a ruling-machine, may also be used in connection with a printing or other machine requiring a paper-feeding mechanism.

Having th us described my invention, I claim and desire to secure by'Letters Patent- 1. In a paper-feeding mechanism, the combination, with a table or support for the paper, of a rotating frictional paper-feeding roll to engage the forward ends of the sheets of paper, pivoted arms by which the said roll is carried, a spring-pressed frictional holdback-bar arranged to bear on the rear ends of the sheets of paper, and feeding-rolls to which the paper is presented by the said frictional roll, substantially as set forth.

2. Ina paper-feeding mechanism, the coinbination, with the rolls B and B and the pulley ZJ, of the shaft G, having the pulleys g and g', the feeding-roll I, its shaft 1'., the pulley z", the belt D', and the cross-belt b2, connecting said pulleys, the paper table or support, and the spring-pressed frictional holdback-bar, substantially as set forth.

3. In a paper-feeding mechanism, the combination, with the frictional feeding-roll I, the arms II, by which said roll is carried, and

the brackets F, of the adjustable springs K, connecting said arms and brackets, substantially as set forth.

4C. In a paper-feeding mechanism, the combination, with a paper-supporting table and a rotating frictional roll I, having a sand or emery feeding-surface, of a spring-pressed holdbaclebar having a frictional surface of rubber, substantially as and for the purpose set forth.

5. In a paper-feeding mechanism, the combination, with the papersupporting table and the frictional feeding-roll I, of the connected arms m, Ithe frictional holdback-bar m', attached thereto, the bar N, the spring n, the hand-lever O, the rod o, and the thumbnut p, substantially as set forth.

G. In a paper-feeding mechanism, the combination, with a table or support for the paper, of a rotating frictional paper-feeding roll to engage the forward ends of the sheets of paper, pivoted arms by which the said roll is carried, a spring-pressed frictional holdbaokbar arranged to bear on the rear ends of the sheets of paper, a carrying-belt t0 receive the paper, feeding-rolls between which the said belt passes, and an upwardly-inclined guide, as P, interposed between the pile of paper and the said 'feeding-rolls, substantially as set forth.

In testimony whereof I afx my signature in presence of two witnesses.

ROBERT BURNET.
